By the time he reached the White House, Bill Clinton's appetite was legend. He loved hamburgers, steaks, chicken enchiladas, barbecue and french fries but wasn't too picky. At one campaign stop in New Hampshire, he reportedly bought a dozen doughnuts and was working his way through the box until an aide stopped him.

Over the past several decades Americans have steadily gotten fatter. Although our increasingly sedentary lifestyles are partly to blame, a big reason for our national weight gain is that we're simply eating more.

Used to be, when you grabbed breakfast on the go, it was a diet disaster: nothing but fat-and-calorie bombs like butter-soaked croissants and jumbo muffins. Now, it's much easier to do right by your body: Fast-food legends like McDonald's and IHOP, as well as newbies like Cosi and Panera Bread, offer surprisingly healthy options that are filling, light, and much easier on your arteries.

Diet drugs have had a rough year in 2010. In October, the U.S. Food and Drug Administration (FDA) nixed not one but two new weight-loss drugs, lorcaserin and Qnexa, because of possible links to cancer (lorcaserin) and heart problems (Qnexa).

Half of all Americans may be diabetic or prediabetic by 2020, a report from an insurance company warned Tuesday. That's an even bleaker projection than the Centers for Disease Control's recent estimate that one in three Americans would have diabetes by 2050.

Drinking too much soda, orange juice, or other sugary drinks appears to increase the risk of developing gout, an especially painful form of arthritis, according to a new study in the Journal of the American Medical Association.

Some nutrition myths bounce around on crazy e-mail chain letters and pop up on goofy evening news reports. Others fuel the sale of rip-off diet books. Some are so accepted they seem hardwired into our brains. Take deep-fried foods, for example. They're universally bad for you, right? Well, no.

When Chris Dolley's sister-in-law asked her to join her in a weight-loss quest, the fast-food fanatic thought to herself she'd do it to help her relative out. It really wasn't about personal goals or missions or health.

The health care bill signed into law Tuesday by President Obama is the nation's most sweeping social legislation in four decades. But it also includes some smaller changes that will directly affect consumers.

Some women avoid drinking calorie-filled cocktails, wine, and beer because they're worried about packing on the pounds. Now, a new study suggests that women who are moderate drinkers actually tend to gain less weight over time than teetotalers.

Among all the ways to change your diet for the better, portion control sounds like the one thought up by a pocket-protector-wearing nutrition nerd patrolling the school cafeteria. To be portion-preoccupied means to be tyrannized by food scales and little tape measures: Is this chicken breast bigger than a pack of cards? Portion policing runs against the ideal of a relaxed, balanced, real-world diet in which healthy food choices bring satisfaction without too much worry about quantity.

One in five teens in the U.S. -- and more than 40 percent of obese teens -- have abnormal cholesterol, whether it's low HDL (good cholesterol); high LDL (bad cholesterol); or high levels of triglycerides, another type of blood fat, according to a new report from the Centers for Disease Control and Prevention.

Doctors have known for years that a woman's risk of developing heart disease rises after menopause, but they weren't exactly sure why. It wasn't clear whether the increased risk is due to the hormonal changes associated with menopause, to aging itself, or to some combination of the two.

Everyone needs carbohydrates, the body's preferred energy source. If you get regular cardiovascular exercise or train for an endurance sport, you need more daily carbs to fuel your workouts and replenish your energy stores.

People who spend a full year on a strict low-carbohydrate diet can lose weight, but they might be happier -- and lose just as many pounds -- if they focus on reducing fat intake instead of carbohydrates, new research suggests.

Salmon, tuna, and other fish are loaded with heart-healthy omega-3 fatty acids, so they must be good for you, right? Not so fast--some types of fish have more mercury than others, and others are harvested from the ocean or farmed in a way that's harmful to the environment.

Cutting daily calorie intake by 30 percent may put the brakes on the aging process, have beneficial effects on the brain, and result in a longer life span, according to a new 20-year study of monkeys published in the journal Science.

Americans talk a good game about wanting to eat well. More than 75 percent claim they want to see more healthy options on restaurant menus. But when it comes time to order, only about half say they actually make nutritious choices, according to a recent survey.

Even if the low-carb diet craze ended up being a bit of a bust, the attention it focused on protein is a good thing. Researchers are taking a closer look at this often ignored nutrient and discovering its hidden health potential.

What if you had a special kind of fat in your body that burned calories instead of storing them -- and it could be activated simply by spending time in the cold? According to three preliminary studies published Wednesday in the New England Journal of Medicine, you probably do.

The recent recall of industrial peanut butter and products that contain it sparked nationwide concern about the safety of eating many popular snack products. That's understandable, considering the average American consumes 3.3 pounds of peanut butter each year, according to USDA data.

You have access to more nutrition information than ever -- from magazines like Cooking Light to the Internet, newspapers, and television. When you add to that the hype about fad diets, the resulting information overload creates more confusion than clarity.

What exactly is it about breakfast that makes it so beneficial? And are all are breakfasts created equal? A study from Pediatrics, published in March 2008, looked at 2,000 teenagers and found that teens who ate breakfast weighed less, exercised more and ate healthier food than their classmates who didn't eat breakfast

The holiday season is a great time for family, friends, and well, old wives' tales: Who hasn't been told to wear a hat because you lose the most heat from your head? Or to keep kids away from poisonous poinsettias?

When you see photos of Cameron Diaz's slim silhouette or Jessica Alba's flat post-pregnancy tummy, you probably wonder just how Hollywood stars stay so lean or snap back into shape so quickly. While many swear their svelte bods come from eating right and exercising round the clock, the truth is that some celebs may go to strange and interesting lengths to get or stay pin thin. Here, the skinny on exactly what the big names do to get red-carpet ready -- from the healthy strategies you'll want to steal to the just plain wacky ideas you'll want to avoid.

What if your doctor told you that even after the weight comes off, your number of fat cells stays the same, and it will be an uphill battle to keep the pounds off? Research published in May 2008 in the journal Nature finds fat cells can shrink -- but they don't go away.

A study from Brookhaven National Laboratory gives us clues as to why some people overeat and gain weight while others do not. Researchers found that even though their stomachs were mostly full, heavier people didn't stop eating. It has to do with motivation and how your brain controls your desire to eat. The study appeared in the February 15, 2008, issue of NeuroImage.

A study says eating too much red meat can increase your chance of getting conditions that lead to heart disease and diabetes.

Children who eat less salt consume fewer sugar-sweetened soft drinks and may significantly lower their risks for obesity, elevated blood pressure and later-in-life heart attack and stroke, according to a study in Hypertension: Journal of the American Heart Association from February 2008.

A Stanford University study, released in May 2007 in the Journal of the American Medical Association, compares the effectiveness of four popular diets -- Atkins, LEARN (Lifestyle, Exercise, Attitudes, Relationships, and Nutrition), Ornish, and Zone -- for women who are premenopausal and overweight or obese. Women on Atkins lost the most weight, although the average loss was only about 10 pounds for 12 months.

There may be a physiological reason why some people do well on low-fat diets while others fail and it's not a lack of willpower. This research was published in the Journal of the American Medical Association in May 2007.

People with diagnosed colon cancer who have received treatment and who eat a "Western diet," high in red meat, refined grains, fat and sugar, are more likely to have a recurrence of colon cancer and die from it, compared with patients who eat a "prudent" diet high in fruits, vegetables, poultry and fish.
